D44H Series (NPN),
D45HSeries (PNP)
Complementary Silicon
Power Transistors
These series of plastic, silicon NPN and PNP power transistors can
be used as general purpose power amplification and switching such as
output or driver stages in applications such as switching regulators,
converters and power amplifiers.
Features
• Low Collector−Emitter Saturation Voltage
• Fast Switching Speeds
• Complementary Pairs Simplifies Designs
• These Devices are Pb−Free and are RoHS Compliant*
